Now I use moly coated leadcast bullets. I do not wash the moly out of the barrel. I run some full power jacketed bullets at the end of the shoot just to keep the feel of the full power loads. The moly eliminates wear of the forcing cone and barrel.
Bill,

Maybe we shot different kinds of jacketed bullets but all those I dug out of dirt banks, sand piles and even baffle boxes showed no evidence of a steel jacket under the copper jacket. I've even seen slide shows depicting the making of jacketed bullets and nothing but a copper alloy jacket with a lead core was ever shown.

YMMV,
Dave
